Hi all, I have a problem with my 05 c4500 . runs fine for a while then injector nock . Now it misses at idle and the balance rates look ok but when it idles rough the injector command for # 4 7 and 8 go from 58 to 0 . all the rest of injector stay at 58 to 60 . I ice picked 7 already and no change .
I cant get a flow rate at idle only in gear . Also runs fine until reaches temp .
any suggestions ? Thanks
